Assignment
Part 1
1. Briefly describe what an event-driven program is.
2. From what you have read in this chapter, describe the difference between a Label control and a TextBox control. When is it appropriate to use one or the other?

Part 2: Programming Challenges
1. Carpet Size
You have been asked to create an application for a carpet sales and installation busi-ness. The application should allow the user to enter the length and width of a room and calculate the room's area in square feet. The formula for this calculation is
Area = Length x Width
In this exercise, you will gain practice using Steps 1 through 6 of the programming process described in Section 1.4:
1. Clearly define what the application is to do.
2. Visualize the application running on the computer and design its user interface.
3. Determine the controls needed.
4. Define the values of each control's relevant properties.
S. Determine the event handlers and other code needed for each control. 6. Create a flowchart or pseudocode version of the code.
Step 1: Describe the following characteristics of this application:
Purpose Input
Process
Output
Step 2: Draw a sketch of the application's form and place all the controls that are needed.
Step 3: Make a list of the controls you included in your sketch. List the control type and the name of each control.
Step 4: List the value of the Text property for each control, as needed. (Remember, some controls do not have a Text property.)
Step 5: List each method needed. Give the name of each method and describe what each method does.
Step 6: For each method you listed in Step 5, draw a flowchart or write pseudocode.
2. Sales Tax
Perform Steps 1 through 6 of the programming process to design an application that gets from the user the amount of a retail sale and the sales tax rate. The application should calculate the amount of the sales tax and the total of the sale.
